The Washington Nationals take the field on Saturday evening in St. Louis ever closer to a National League East division title, with their magic number now sitting at two despite a 12-2 loss on Friday evening. A Washington win and Atlanta loss would mean a division crown for Davey Johnson's club, who lead the Braves by four games with five to play. Here is tonight's starting lineup, via @NationalsPR:

Tonight's lineup: Werth, rf; Harper, cf; Zimmerman, 3b; LaRoche, 1b; Morse, lf; Desmond, ss; Espinosa, 2b; Suzuki, c; Zimmermann, p.
